Is a catch can a good investment for a supercharged motor? I have an ls6. Just wondering it it really helps or I should spend money elsewhere.

Yes it is a good idea. Get a good one, especially since you are using forced induction. I personally went with a mighty mouse setup.

AltitudeCO

+1 for the MM setup

Podium

That's the brand I would go with

AltitudeCO

Had it on multiple cars, great setup. Worth the investment
What is your SC setup out of curiosity?

Podium

Its an 01z with A&A TI kit. Full exhaust with a cam.

-10 vents off both valve covers to a vented can... Best way you can do it, vented to atmosphere.

Like TTBlueZ06 said -10 or -12 bungs welded to your valve covers and run them to can. Easy to do.

I'll add that bung location is important. All of the oil in the head runs to the rear, under acceleration so I try to put them forward of the very back and up top, of course. When space permits, I also prefer to weld in a baffle to help prevent oil from coming along with the crankcase gases. The larger diameter, the lower the gas velocity, which also helps. Also, no diameter ever seems large enough when the motor gets hurt.

I've read that. Can you Y them together or run separate lines to the can? What about the pcv?

I think I'm going to order a Mighty Mouse can set up this week.

Podium

Which can did you go with and how did you run it?

Avoid bring the lines to a Y because you will then restrict flow. Say you have a 10AN bung on each valve cover but they Y into a single 10AN or 12AN, it will only flow as much as the single line they Y into.

I used the PCV can when I was supercharged but now I have a PCV can and a draft can. PCV can is installed between the intake manifold PCV barb port and one valve cover port(dirty side). The draft can is installed between the other valve cover port and a 10AN bung I welded on my turbocharger intake tube(clean side).

I havent talked with David yet but it looks like with his system you plug the ls6 valley pcv?

Im hoping to run one can.

David@MMS

hello!

happy to answer any specific questions, chipping away at any voicemails now as well.

Turpid porpoise

David can answer this but according to his diagrams, yes you do.

Podium

I spoke with David and he told me that instead of us8ng the driver valve cover, you can use the ls6 valley pcv barbed port to the supercharger. This is what I plan on doing to keep the install clean

David@MMS

the valley plate and some ls cars and trucks, the driver cover are most commonly used as the pcv system flow regulation point, controlling manifold vacuum application to the crankcase.
-when we have the catch can take over this job, as is the case with my PCV can (this can comes in most of my wild systems), these ports are no longer required for their original job, and are usually capped but sometimes need to be used as a nice baffled point for fresh air supply
